From the Wikipedia article
The Bay Area Ridge Trail is a multi-use trail along the hill and mountain ridgelines surrounding the San Francisco Bay Area, in Northern California. It is planned to extend 550 miles (890 km); As of May 2025, 427 miles (687 km) have been established. When complete, the trail will connect over seventy-five parks and open spaces. The trail is being developed to provide access for hikers, runners, mountain bicyclists, and equestrians. It is intended to be accessible through trailheads near major population centers, but the trail extends into more remote areas. The first trail section was dedicated on May 13, 1989.
